Овуляция: когда ждать, если цикл 28 дней, но тесты полосатые? 10 попыток забеременеть

These ovulation test strips are frustrating, and so is my ovulation timing, or lack of maybe? Thought id ovulate around day 14-15 bc i have a 28 day cycle but maybe i didnt and im going to ovulate later. TTC is so hard! 😮‍💨 currently on cycle 10.
